Ipomoea plant named ‘ISGDP01-1’

ABSTRACT

A new and distinct  Ipomoea batatas  cultivar named ‘ISGDP01-1’ is disclosed, characterized by dark greyed-purple palmate shaped foliage. Plants have a semi-compact, mounding habit and produce many lateral branches, without pinching or chemical growth regulators. The new cultivar is an  Ipomoea batatas , typically suited for ornamental container and garden use.

Latin name of the genus and species: Ipomoea batatas.

Variety denomination: ‘ISGDP01-1’.

BACKGROUND OF THE INVENTION

The new variety originated as a chance discovery by the inventor, SteveJones. The variety was discovered as a naturally occurring whole plantmutation from an unnamed, unpatented proprietary variety of Ipomoeabatatas. The new variety was discovered in August 2018 at a commercialgreenhouse in Santa Paula, Calif.

After selecting and isolating the new cultivar, asexual reproduction ofthe new cultivar ‘ISGDP01-1’ was first performed by vegetative tipcuttings in a commercial greenhouse in Santa Paula, Calif. in October2018. ‘ISGDP01-1’ has since produced several generations and has shownthat the unique features of this cultivar are stable and reproduced trueto type. Typical asexual reproduction of the new variety is byvegetative cuttings.

SUMMARY OF THE INVENTION

The cultivar ‘ISGDP01-1’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘ISGDP01-1’. These characteristics incombination distinguish ‘ISGDP01-1’ as a new and distinct Ipomoeacultivar:

-   -   1. Vigorous growth.    -   2. Deep, dark greyed-purple foliage color.    -   3. Semi-compact, mounding habit.    -   4. Very well branched.

PARENTAL COMPARISON

Plants of the new cultivar ‘ISGDP01-1’ are similar to the parent in mosthorticultural characteristics. However, ‘ISGDP01-1’ differs in thefollowing:

-   -   1. The new variety has a more vigorous growth habit than the        parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘ISGDP01-1’ can be compared to the commercialvariety Ipomoea batatas ‘Sweet Caroline Purple’, U.S. Plant Pat. No.14,912. Plants of ‘ISGDP01-1’ are similar to plants of ‘Sweet CarolinePurple’ in some horticultural characteristics, however, plants of‘ISGDP01-1’ differ in the following:

-   -   1. The new variety has a more compact growth habit than this        comparator.    -   2. The new variety has deeper purple leaves than this        comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘ISGDP01-1’, seen in the left side of the photograph.The plant on the right of the photograph is the abovementionedcomparator variety ‘Sweet Caroline Purple’. Both plants areapproximately 8 weeks old, from an unrooted cutting, shown in a 1 gallonpot.

FIG. 2 illustrates a close up of the foliage of both the new variety andthe abovementioned comparator. Foliage of the new variety is on the leftin FIG. 2, foliage of this comparator is seen on the right side of thephotograph. Plants were grown in a greenhouse in Santa Paula, Calif.

The photographs were taken using conventional techniques and althoughcolors may appear different from actual colors due to light reflectanceit is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The R.H.S.Colour Chart, 2007, except where general terms of ordinary dictionarysignificance are used. The following observations and measurementsdescribe ‘ISGDP01-1’ plants grown during the Spring months in agreenhouse in Santa Paula, Calif., under bright, unshaded conditions.Average day temperatures were approximately 20° C. to 26° C. and theaverage night temperature was approximately 15° C. to 18° C. Noartificial light, photoperiodic treatments or chemical treatments weregiven to the plants. Measurements and numerical values representaverages of typical plant types.
